Sony's UMD failures (we haven't seen any UMD news since July) don't necessarily mean that the PSP is a failure for movies. It just means people hate the UMD. Now Sony's in discussions with Amazon, Movielink, and CinemaNow in order to strike a deal for PSP movie downloads.
What do you think of this? We think that a rental service, where you can pay, say, $25 for an all-you-can-watch download scheme for your PSP would be great. People probably wouldn't want to purchase a second version of Batman Begins just so they can watch it on their PSP when they can rip the DVD and shove it on a memory stick themselves. A concept which had a big part to do with why the UMDs failed.
